Monitoring Non-Invasive Operations Non-invasive operations, which do not disturb existing materials, include setup, field reconnaissance, biological surveying, geophysical and topographical surveying, and decontamination, removal of trees and brush, and miscellaneous Support Zone activities. If during the initial evaluation the Incident Safety Officer deems it necessary, one member of the field team will monitor the ambient breathing zone air continuously with a PID, which detects total hydrocarbons present in the air. The PID will be calibrated each day prior to fieldwork. A spectrophotometer or gas chromatograph should be used for more precise readings. A radiation survey meter will be used to monitor ionizing radiation at selected areas where radioactive contaminants may have been disposed. |
